Breaker box look correct?

[SailingHome]

I've never seen one like this just one strip at the top. No buses for hot and neutral is that correct? Is this for an RV or common here? New Cir.2021

[bearded_bluto]

I see a neutral bar on top and a ground bar on left.  Use multimeter to be sure.  I'm no expert, but the wire looks too small for your main breaker 50A and the 32A one. Very colorful. Looks like a ouchy or soon to be funeral to me.

This ^^^ 

 

BUT!!!

 

The bar to the left of the incoming breaker should be the NEUTRAL.

 

The bar at the top which is bolted to the case should be the EARTH/GROUND.

 

Wire sizes need to be checked.

 

I also note that there is no earth-leakage protection (as a minimum an RCBO incoming breaker), this is a vital safety feature.

 

IMHO It's a total mess, I recommend getting a competent sparks in and re doing the whole shebang (with emphasis on the "bang")!

Are you saying that not only are some of the neutrals bonded to the ground, but that the case itself is neutral? Which would especially within air conditioner give rise to considerable shocks? If it had been set up that way from the beginning with zero ground wires what would be the implications? Are there any indications that some of the neutral go to the correct neutral bar?

Wire colours mean nothing!

 

You won't (ok shouldn't) get shocks from the neutral, but if you install an RCBO with the box as it appears to be wired then it won't stay switched on.

 

But I see a lot of grey wires on what is supposed to be the ground bar, and green/yellow wires on what is supposed to be the neutral.

 

Working out exactly what is going on is nigh on impossible from a photo, you need to be hands-on with some basic test gear.

 

The only way to be certain is to disconnect everything, and with the power off of course buzz-out (meter, bulb and battery) the neutrals from each circuit.

 

Whilst you are at it those taped joints have to go!!! Particularly the one connecting a brown and blue (what did I say about wire colours).

What do you replace them with?  Photo please if not too inconvenient.  Thank you.

Well, in fact, what's the new air conditioner was put in the shocks got greater and greater which is all explainable according to the IEEE and even Thai sources. Remember that none of those green wires were there. If none of those green wires were there and nothing else was moved what are you looking at?

A complete mess!

 

If you are getting shocks, time to turn off at the mains and get a competent sparks in!!!!!!!!!

 

Is there a ground rod anywhere? Where is it connected to??

As a Brit I would use Wago connectors.

 

Failing those, wire nuts (not permitted in the UK)

... Yes. I believe the electrical code calls for workmanship but remember those are old brittle wires from an old fuse box being reused and that location can't be reached in an emergency. However I don't think Thailand is as advanced with their electrical code yet to say that anytime work is done it must be brought up to code.

Specifically I'm wondering if you removed those green and black ground wires that were added for my safety on the left hand side don't you see some neutral connected to ground as if Willy nilly any bus is OK or is that just my eyes deceiving me?

[Crossy]

Sorry. without being there I really can't say what is going on.

 

WIRE COLOURS MEAN NOTHING!!!!! For all we know he's used brown for earth.

 

Do you have any test gear (a simple multimeter would do)? A neon screwdriver would also be handy.

 

Seriously, you need to get a man in before someone dies or a conflagration starts. Try talking to your local PEA/MEA office, many of their chaps are not averse to a bit of moonlighting and they are likely to be decently competent.

As @Crossy said it’s a total mess as are the cables coming in. None of the wires have brittle insulation. There is no code enforcement in Thailand and often never an inspection.

 

you don’t say where you are located, in the northeast I have the contact information of an electrician. Your install looks to have been done by a blind plumber in the dark. It certainly isn’t the worst but it is getting there.

He was probably wearing boxing-gloves too.

Only juristic offices are qualified and certified other than very large company electricians. That I know of there are no inspection services as those that I can find won't come. "Electricians" IE Western qualified to higher standards, or Thai who routinely contract to do electrical work are not an authority.  What does the condominium act say of the Juristic body if they install electrical in the room and don't check the box?

Bangkok, but thanks for the offer 🙂 I now a lot of electricians and EE's

Get one of them in to have a look.

 

And then ask them to fix it if they don't run away screaming!!
